So I was recently shopping for a new zero turn mower, mostly looking at eXmark Radius and Kubota Z400 series.
I ended up buying a Z700. I was in a bit of a hurry and didn't have my customary time to do research, and there's
something I still want to understand.
The Z400 and the eXmark units have the Hydro Gear transaxles (Commercial Products - Hydro-Gear), the zt-3600 in the case of the Kubota z400, and the zt-3400 for the Radius X (I think, not sure).
The Z700 has the Parker HTG14 (https://ph.parker.com/us/17601/en/htg-series-hydrostatic-transmission).
Looking behind the general theme of integration and durability of the components of these motors, I wanted to understand ... redundancy. My dealer made a comment about how some of these mowers have two units, and some have one. And, not having seen the interior of any of these mowers, I don't understand it. Don't all of these mowers have a pair of [pump + motor] boxes, one for each wheel? What is there "one of" in these? Shared hydraulic oil reserves?
Just assume I'm clueless, because I am.
Thanks for shedding some light on the how these things pull together. Note that I'm NOT looking for "how hydraulic motors" work, I've watched those videos
I'm looking at how these units are integrated into the mower overall, what they share, whether there is redundancy, and what makes one design better than another after you look _past_ the basic pump+motor combo. I'm hoping one of you reading this works on these for a living and can paint a picture of what you've seen.
